摘要：摘除整株叶片的1 3、2 3、3 3叶量对元宝枫生长影响的研究表明:不同采叶量和采摘时间显著影响着元宝枫的株高、地径、叶面积和叶生物量干质量,而对冠幅影响不显著。随着采叶量的增加,对元宝枫的影响显著加强;采叶时间的影响依次是6月>4月>8月。4月采叶3 3显著抑制株高、地径、叶面积和叶生物量干质量增长;6月采摘对株高和地径的生长影响显著,但对叶面积和叶生物量干质量的影响不大。
The effects of harvesting 1/3 of the leaves, 2/3 of the leaves, and 3/3 of the leaves on the growth of A.truncatum were studied. The results showed that the harvest quantity and harvest season significantly affected the tree height, base diameter,leaf area and leaf biomass dry weight, but there was no significant difference on the crown. There were positive effects of harvest quantity increase on growth of the tree. The effects of harvest leaf in June were more than in April, and in April were more than in August. Harvest 3/3 of leaves in April significantly harmed the increment of tree height,basal diameter,leaf area and leaf biomass dry weight. Harvest leaf in June significantly affected the increment of the tree height, basal diameter,but there was no significant difference on leaf area and leaf biomass dry weight.
